Method and means for making master models

ABSTRACT

An apparatus for carrying out the automatic machining of threedimensional lines and surfaces for making a master model comprising three components which are controlled to move in a straight line, including an X-component which has a horizontal longitudinal X-movement, a Y-component which has a vertical Ymovement, and a Z-component which has a horizontal Z-movement at 90* to the X-movement, a tool operatively mounted on one of said components, power means operatively connected to each of said three components for moving the components in said controlled straight line movements, a signaling device for each of two of said components for controlling the power means therefor, a first source of two-dimensional data mounted on one plane, and a second source of two-dimensional data mounted on another plane perpendicular to said one plane, and a sensing element for each of said signaling devices which engages and is responsive to one of said two-dimensional data sources, whereby the power means controlled by the signaling devices cause their respective connected components to move precisely in accordance with the two-dimensional data, thereby producing a three-dimensional relative movement between the tool and the workpiece.
